A scientific basis for tailoring the exercise load of the Thoroughbred to reduce fracture risk

摘要

A major role of the skeleton is to support the body and also to provide a system of levers upon which muscles act to cause movement and locomotion. The architecture of the skeleton is optimised both through evolution and in response to real time demands for energetic efficiency. Structures are designed for optimal function using both material properties and geometrical design to arrange those materials in relation to functional demands. Bone, both as a tissue and an organ system is optimised for function. The material comprises a composite of inorganic mineral and organic protein, to maximise strength in diverse loading conditions. This material is arranged in relation to structural demands to form the specific bones of the skeleton. Some bones withstand bending, others torsion, tension and compression. The horse has evolved for speed and this has then been exploited further by training for specific elite athletic activities. The loading of the skeleton during peak athletic activity and in trainingpresents risk of fracture.
